SPARK PLUG NUMBERING SYSTEM
Bosch has introduced a new numbering code for its com-
plete line of spark plugs. The new code is shorter, therefore
easier to use. The following charts will assist you in making
the change-over easily and effectively.
IMPORTANT: The new code has a different heat range
identification system.
High number hot plug
Low number cold plug
